Default underdrive pulley

I am about to get an underdrive pulley. I am confused on an issue though. How much power will I get from an 25%?

Normally you see around 8-10 flywheel with a 25% under drive pulley alone. If you have a auto car I recomend going to the over dirve alternator pulley also so you dont have any charging issues at idle (auto's idle lower than sticks). With the over drive alt pulley you should see 6-8 flywheel. Tourque you should see around 12 ft lbs all through the RPM range.

i would recomend the SLP or the ASP
